Hi All
I am trying to get the coefficients values for AM-AM curve fit to Rapp model function.
Using the toolbox of curvefit I generated a script.
However, I could not get the values using the command
k = coeffvalues(fun). where k is valus vector fun is function of Rapp model.
Error is : undefined function 'coeffvalues' for input arguments of type 'fittype'
Appreciate your help and assistance
Kind Regards
Av

Based on the error, it looks like you are passing a fittype object instead of a cfit or sfit object. Look at the example in the MatLab documentation.
